示例1: jumpToLine
//jump to line n in functions
bool MapBuilder::jumpToLine(int n, ifstream &lookFile, ofstream &putFile){
bool newLine = false;
lookFile.seekg(ios_base::beg); //set cursor to the beginning
int counter = 0;
while((n < counter) && (!file.eof())){ //search for n new lines
if(findsNLChar(lookFile)){ //if you find a new line
counter++; //count that
}
}
if(!lookFile.eof()){ //if we got to the end before making n lines
return false; //we never made it
}
putFile.seekp(lookFile.tellg()); //put the putting pointer to where looking pointer is
return true; //successfully got to line n
}示例2:
bool
csv_fwrite (ofstream &fp, string src)
{
if (fp == NULL || fp.eof())
return false;
fp << '"';
for (unsigned int i = 0; i < src.length(); i++) {
if (src[i] == '"') {
fp << '"';
}
fp << src[i];
}
fp << '"';
return true;
